Sean Cox is an Assistant Professor in the mathematics department at Virginia Commonwealth University.

Cox’s research interests are in forcing, combinatorial set theory, inner model theory, and applications of set theory.

Much of his research focuses on the structure of normal, $\sigma$-complete ideals, such as the nonstationary ideal on a regular uncountable cardinal. He is particularly interested in generic elementary embeddings arising from such ideals and towers of ideals. This topic is central to most branches of set theory, including large cardinals, forcing, and inner model theory.

His results include both relative consistency results (using both forcing and inner model theory), as well as the theory of Martin’s Maximum and the Proper Forcing Axiom.

Sean obtained his PhD at the University of California, Irvine in 2009 under the supervision of Martin Zeman. He was a postdoc at the University of Muenster (Germany) from 2009-2012.
